[Fiware-lab-help] Problem Allocating IP

[fiware at in4apps.com]

Hi! I'm trying to allocate an ip, I have 1 available, but when I try  
to allocate, it shows me this error:
Error allocating IP address. Cause: 400 Error
{"badRequest": {"message": "No more floating ips in pool net8300.",  
"code": 400}}

Any Help?
